Specification of Letters Patent.

Patented Nov: 4, 1919.

Application filed August 16, 1817. Serial No. 186,529.

To all whom it may concern Be it known that I, LOUIS H. PERLMAN, a residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Wheels; and I do hereby declare the following to be a full,-

clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 'ihrsinvention relates to improvements in demountable rims or wheels of the type ordinaril employed as carrying wheels for automobi es.

The primary object in view is the improving of the means of anchorage for the rim locking means, having reference more particularly to the type of locking means disclosed in detail in my co-pending application Serial No. 150,487 filed February 23, 1917.

With this and further objects in view as will in part hereinafter become apparent and in part be stated, the invention com prises certain novel constructions, combina-- tions and arrangements of parts as subse quently specified and claimed.

In t e accompanying drawing,

Figure 1 is a transverse section through the peripheral portion of a wheel and de mountable rim embodying the features of the present invention.

Fig. 2 is a vertical section taken on the plane indicated by line 2'2 of Fig. 1.

Fig. 3 is a horizontal section taken on the plane indicated byline 3-3 of F ig. 1, looking'upward, a fra ment of the rim being seen. in inverted p an.

Fig. 4 is a perspective view of one of the lock-receiving members detached.

Figs. 5, 6 and 7 are views of an embodiment of the lock-receiving element detached.

. indicates the Figs. 8, 9 and 10 further embodiment.

Fig. 11 is a plan view, of a fragment of the inner face of a modified form of rim.

Fig. 12 is a cross section taken on the plane indicated by line 12-42 of Fig, 11. Referring to the drawing by numerals, 1 felly, 2 the fixed rim, and 3 the-demountable rim of awhcel of the type fully disclosed in my above-identified c0- pending application. For purposes of rendering the disclosure self-contained in this application it will be seen that the wheel are similar views of a portion is provided with locking apparatus, preferably several in number, spaced uniformly about the wheel and consisting essentially of a radially moving bolt 4 slidmgly mounted in a sleeve 5 anchored in the peripheral portion of the wheel, the sleeve being engaged by a nut 6 arranged to actuate the bolt 4 by having an underhanging annular flange 6 engage a shoulder? at the inner end portion of the bolt 4. A

cotter-pin-retained nut 8 is arranged beneath the flange 6 in engagement with the reduced projection of the bolt, so that when the nut 6 is threaded radially inward the bolt 4 will be retracted and reverse movement of the nut 6 will project the bolt 4. A flattened portion 4' is provided on the bolt 4 to engage a correspondingly flattened portion within sleeve 5 to prevent rotation of the bolt and to keep its outer end properly alined with the cooperating part of the rim 3. The bolt 4 is shown with its outer end formed with so that the rim 3 is provided with a correspondingly tapered recess elongated in the direction of the circumference of the wheel, but, of course, the upper may be otherwise formed, as, for example, as seen in my above-nicntioned co-pending a plication. In that event, the form of 100 receiving means on the rim would have'to be correspondingly formed, As the said co-pending application covers the locking means itself, except for the s )eoific form of taper at the outer'endof t e bolts, it is understood, ofcoursc. that this invention -1s more partmularly directed to the lock-reend of the bolt 4 continuous annular itself.-

already in use the lm-k-rccciving means such as shown in .in ro-pr nding application.

The rim 3, llu-rcl'orc, cra'hly uniformly spaced points. the perforations being of a size and shapito snugly re ceivc the rcctangular upstandiiig bos9 carricd by plate 10. The plate 10 is preferably disk-shaped and formed integral .with theboss 9, and

a recess-11 is formed hrough the is perforated at pref-- of ll parts of; gtho bolt-receiving recess.

gntcd in the direction of the circum fcrcncc,

of the rim so its to allow of aslight variation iustmont of the rim when it is being tho rs l1 bcino of u, lcn-gth in out the dimensions oi the tapered cud bolt. Tho plate 10 is woldcd or othorwise npproprio olly fixed to tho base of the rim, cud the boss 9 proportioned to suugl fill tho rcspcctive npcrturc in the rim. t will thus be soon that the lock-rccciving moons of the rim may be applied as well to rims now in use us to new rims. The sperturcs for receiving the bosses 9 are positioned midway of the width of the rim, The stop flange on the rim 2, however, is so spaced relative to the median line of the rim that the effect is tho some as if the recess 11 were off of the said median line in the direction toward the outer face of the wheel, whereby when the bolt is forced outwardly into the recess 11 it will act to wedge the rim axially against the stop flange! and even after the rim has been seated firmly there will still be a sullicient lateral offset of tho lock-receiving portion of the rim (that is,'thc material at tho respective side of recess 11) to enable the bolt 4- to tend to further crowd the rim axiully against the stop flange when the bolt is further pressed radmllyoutwnrd.

In Figs. 5, 6 and 7, I have illustrateda,

further embodiment of the lock-receiving means wherein the cl iskshsped plate 10" is employed having the circular boss 9 and being formed with the recess 11", all of said corresponding in function and substantially in form with the respective parts 10, 9 and 11 above described. I

In Figs. 8, Q, and 10, I have-shown a modificd embodiment of the invention in which a plate 10 is provided corresponding in form and function to thBg late 10 except that the plate IOllS ii'ectnng or. The, 1.0 is provided with the boss 9 having the recess 11, both corresponding in form and function to the respective parts 9 and 11.

In the application of .the lock-receiving means, it is obviously essential that the,

groove .11 shalllbe accurately ositioned in the line of the clrcumference o thernn and not set at an ingle to such plane. Even B4 slight angular disposition of the parts would be injurious and interfere with the effective operation. of the parts. It is this obviously preferable to have the apertures in the base offthc rim and tho corresponding bosses either of rectangular :Eorin or other polysidcd form so as to insure the pro or location is circular form of boss may also housed with theorem located, and this form of boss will be ound dcsirablenvherc the operator who is ap lying the part has facility for drilling a 010 but has no facility for punching one.

In the above described embodiments of the invention, the lock-receiving groove member is made of a separate piece of material from the rim and inserted through an aperture in the rim. The same results may be obtained so for the short segr'nental sections of grooves spaced apart about the rim are concerned by -stmnping such sections of grooves directly in the rim aftcrthe manner seen in Figs. 11 and 12. In these figures, the rim 3' is stamped to form the'recess of groove 3 the material of the rim being pressed radially outward to form the recess. In the course of pressing the recess 3 thenmterial of the base of the rim may be somewhat reduced in thickness, but the reduction is comparat'ively slight and no attempt at showing such reduction is made in te drawings,

Care is exercised to see that the projection 3' I edges of the rim in such manner as to on able the rim to be applied with either edge first, It is also noted that the roove sections 3 are segmental since t ey. extend part the way in the direction of the circumference of the rim and are of a greater length r than the corres onding dimension ofthe V ion shaped lock wich is designed to engage t e them. This relative proportion enables locks to engage the groove sections even' though, the section may not be spaced exnctlv the same distance apart as the locks.

hat is claimed is 1. In a demountabei rim structurepthe,

combination with an a ertured demountable rim, of a part having colt-receiving means the said part being adapted to exten through and fill the aperture in the rim, and

the lock-receiving means bein of ater length than width and being'dlspose with its length extending circumferentmlly of the rim.

2. In a demountablerim, the combination with a rim, of a plate secured thereto and having a boss extending through the rim, the boss being formed with lock-receivin means of greater length than Width on with the lcngth'of the Iock receiVing" means? 1 extending circumferentially of the In a (lo-mountable rim, the comblnation with a rim, of a plate secured to the inner face of the rim and having is boss oi metangular form extending outwardly through the rim, the said boss being formed with an elongated revess zulupted to receive rim leeking means, the recess being elongated eir cumferentially of the rim.

4. In a (leinounteble rim, the combination with a rim, of a plate secured to the inner face of the rim and having :1 boss of ree- (angular form extending outwardly through 10 the rim, the said boss being formed with an eumterentiully of the rim, the recess beingof V-shepe in cross section.

In testimony whereof I uflix my signature 15 in presence of two witnesses.
